The Megasonic single and dual nozzles (600kHz to 5 MHz) transmits the sonic wave into the flowing water and its surface. With up to 35 W concentrated on a small point of only 4 mm results in superb results in contactless cleaning. The dual nozzle works with two distinct frequencies and provides removal of a wider range of particles.
The single and dual nozzles are used in cleaning of single wafers, masks, LCD panels and substrates.
SONOSYS®沉入式发振器可使用于各种容器与介质并具有最大的使用弹性, 不锈钢本体披覆PVDF抗化性, 可做成4", 6", 8" 晶圆大小的有效面积, 适应不同频率及最高输出功率至2000瓦以满足多种应用及架构.
When it comes to small and smallest particles on surfaces, the use of Megasonic is known for years (i.e. ultrasonic waves in the higher frequency range, usually 400kHz upwards). Most notably, if particles smaller 1 micron shall be removed, the method is quite successful. Thereby, it doesn’t damage the sensitive micro- and nanostructures of the substrate, since the cavitation bubbles are much smaller than with traditional ultrasound. Typical applications are wafer cleaning, MEMS and microstructure cleaning and etching, removal of photoresist in photo masks and many others.
The latest trends with this technology look at even higher frequencies, that is more than currently 5 MHz for even smoother cleaning and the control systems become more advanced. With future generations it will be possible to digitally control the nozzles, allowing for a wide control range and very short cycles of on/off times.
Nowadays nozzles are available in a single or dual versions, meaning, that either one frequency – e.g. 1MHz – or a combination of two frequencies – e.g. 1+3 MHz – is applied. The fully metal-free design with a housing made of PTFE (Polytetrafluoroethylene ) allows to meet the high requirements in the semiconductor industry. The medium passes by at the internal piezo ceramic which modulates the high frequency ultrasound into the water stream and is finally focused by a quartz glass nozzle outlet with a width of approx. 4mm, resulting in a Megasonic jet stream to effectively cleaning your surface.
This way, for example a 200mm/8” Si-wafer can be cleaned within 1 minute from silicon nitrite (Si3N4) and silicon dioxide (SiO2) particles, depending on cleaning media and temperature up to a PRE of >= 98%.
